This video captures the moment. It appears that the building was struck by two missiles.The tower was part of the Zafir complex and housed almost fifty families. Residents had reportedly received warnings to leave the building, but medical officials said 17 people were injured, four of them children.

At least ten Palestinians were killed in relentless Israeli airstrikes across the Gaza Strip on Saturday, mostly women and children, Ma’an News Agency reported.Human rights groups have condemned Israel’s deliberate targeting of civilian homes and infrastructure, but amid international complicity and silence, it has continued the practice unabated.

If Israel’s attacks on Gaza had been on the United States, it would be the equivalent of about 375,000 American deaths. That means Gaza has experienced about 125 “9/11s” since 7 July. This is hardly surprising, since Israel has dropped the equivalent of an atomic bomb on Gaza.

Building housed Fatah officials

Israel has claimed that the building that was home to hundreds of people “was a center of terror activity, and housed several Hamas operation rooms.” It presented no evidence to support these claims.

Fatah is the faction headed by Palestinian Authority de facto leader Mahmoud Abbas who is in de facto alliance with Israel through the PA’s so-called “security coordination” with the Israeli occupation army in the West Bank.

The officials who lived in the building included Ibrahim Abu al-Naja, a senior Fatah leader in Gaza; Nazmi Muhanna, a Fatah leader and the head of the border crossings administration for the PA; and Rawhi Fattouh a former advisor to Mahmous Abbas.

GAZA CITY, Gaza Strip (AP) — Israeli airstrikes leveled a seven-floor office building and severely damaged a two-story shopping center in the Gaza Strip early Sunday, signaling a new escalation in seven weeks of fighting with Hamas.

The strikes in the southern town of Rafah came just hours after Israel bombed an apartment tower in Gaza City, collapsing the 12-story building with 44 apartments.

The targeting of large buildings appears to be part of a new military tactic by Israel. Over the weekend, the army began warning Gaza residents in automated phone calls that it would target buildings harboring “terrorist infrastructure” and that they should stay away.

A senior military official confirmed that Israel has a policy of striking at buildings containing Hamas operational centers or those from which military activities are launched. The official said each strike required prior approval from military lawyers and is carried out only after the local population is warned.

However, he said, there was now a widening of locations that the military can target. The official spoke on condition of anonymity because he was not permitted to discuss the matter with reporters.

Meanwhile, Gaza militants continued to fire rockets and mortar shells at Israel, including at least 10 on Sunday, the military said. That was in addition to more than 100 on Saturday, most aimed at southern Israel.

Elsewhere, five rockets were fired from Syria and fell in open areas in northern Israel. It was not immediately clear whether they were fired by pro-government forces or rebel groups.

Amid persistent violence, Egypt has urged Israel and the Palestinians to resume indirect talks in Cairo on a durable cease-fire, but stopped short of issuing invitations.

Several rounds of indirect talks between Israel and Hamas have collapsed, along with temporary cease-fires that accompanied them. The gaps between Israel and the Islamic militant group on a new border deal for blockaded Gaza remain vast, and there’s no sign either is willing to budge.

The Israeli military said it had carried out some 20 strikes on Gaza since midnight Saturday.

In Rafah, Israeli aircraft bombed the seven-story Zourab building, which houses an office of the Hamas-run Interior Ministry. Witnesses said the building was leveled and that the strikes caused severe damage to nearby shops, homes and cars.

Another strike hit a nearby shopping center with dozens of shops, sparking a fire that gutted the two-story building. After daybreak Sunday, smoke was still rising from the site as shop owners inspected the damage. Windows and doors had been blown out in nearby buildings.

The military said the two buildings were attacked because they housed facilities linked to militants, but did not provide details. The Gaza City apartment tower toppled Saturday was targeted because a Hamas command center operated from there, the army said.

Palestinian health official Ashraf Al Kidra said two people were killed in a pair of airstrikes near a coastal road on Sunday, including one on a group of people coming out of a mosque after morning prayers. Two more fatalities were registered when a motorcycle following a car evacuating the wounded from the strikes was targeted.

The U.N. estimates that more than 17,000 homes have been destroyed or damaged beyond repair since the war began on July 8. In some of the attacks, family homes with three or four floors were pulverized.

However, the weekend strikes marked the first time large buildings were toppled.

Since the fighting began, Israel has launched some 5,000 airstrikes at Gaza, while Gaza militants have fired close to 4,000 rockets and mortars, according to the Israeli military.

More than 2,100 Palestinians, including close to 500 children, have been killed, according to Palestinian health officials and U.N. figures. Israel has lost 64 soldiers and four civilians.

Israel says it is targeting sites linked to militants, including rocket launchers, command centers and weapons depots. The U.N. says about three-fourths of the Palestinians killed have been civilians.

How many bombs has Israel dropped on Gaza?

A few days before he was killed trying to disarm an unexploded Israeli missile, Hazem Abu Murad, the head of Gaza’s bomb squad, estimated that Israel had dropped between eighteen to twenty thousand tons of explosives on Gaza since 7 July.

As I write, Israel has resumed its heavy bombardment after a nine-day truce ended without a long-term ceasefire agreement.

If Abu Murad’s estimate is right, then the explosive power Israel has fired on Gaza by land, sea and air so far is roughly equivalent to one of the atomic bombs the United States dropped on Japan in August 1945.

The bomb dropped on Hiroshima was rated at 13 kilotons – the equivalent of thirteen thousand tons of high-explosive TNT – while the bomb dropped on Nagasaki was rated at 21 kilotons.

Abu Murad, who died along with five other people on 13 August, estimated that about one thousand tons of unexploded munitions remained. There are more than 1,900 people killed in the ongoing Israeli assault – that is more than one out of every thousand of Gaza’s nearly 1.8 million residents.

Israel constantly publishes claims about how many mortar shells or rockets have been fired from Gaza – it claims for instance that 3,360 rockets were fired from Gazabetween 8 July and 6 August.

It is well known that the rockets have caused minimal damage and casualties, and most fall in so-called “open areas.”

But even the number, which is supposed to sound impressive and justify the attack on Gaza, is actually minuscule compared with the volume of ordnance Israel fires into Gaza.

Estimates based on partial information from Israeli sources indicate that Israel has fired tens of thousands of artillery shells into Gaza and dropped a bare minimum of six thousand tons of bombs from the air. Abu Murad’s on-the-ground estimate is certainly plausible.

Israeli sources provide some information that allows us to generate a more accurate picture of the quantity of explosives Israel fired, and why their impact was so lethal and indiscriminate.

Indiscriminate artillery fire

The easiest type of munition to estimate is artillery shells. On 14 August, Haaretz published the following information, sourced to a “senior official of the general staff” of the Israeli army (emphasis added):

The estimated cost of the total ammunition used in Gaza fighting is estimated at about 1.3 billion shekels [$370 million]. According to the army’s figures, 39,000 tank shells, 34,000 artillery shells, and 4.8 million bullets were supplied during the fighting. Senior military figures estimate that land forces alone used at least 60 percent of the 5,000 tons of ammunition given to them, but the IDF [Israeli army] cannot yet evaluate it accurately.

According to the same senior staff officer, most of the ammunition came from Israeli production lines. Some of the ammunition was purchased from the US during hostilities, within the “advance placement” program. Additional ammunition and fighting equipment, along with medical equipment, were also ordered during hostilities, using an expedited procedure via the Defense Ministry.

Israel expert Dena Shunra notes that the concern here is cost – this is a move in budget negotiations in which the army seeks more money – and that is the context in which the numbers are revealed.

If, as reported, 60 percent of the stores were used, that would mean 23,400 tank shells, 20,400 artillery shells and 2.9 million bullets. That is almost two bullets for every man, woman and child in Gaza.

The most common artillery munition Israel employs is the 155 mm M107 high-explosive shell, according to a 2007 Human Rights Watch report titled “Indiscriminate Fire”:

M107 shells are extremely deadly weapons. The expected lethal radius for a 155 mm high explosive projectile is reportedly between 50 and 150 meters and the expected casualty radius is between 100 and 300 meters. IDF [Israeli army] officials have said that the error radius for a 155 mm shell is usually 25 meters. Therefore, if shells are lobbed as close as 100 meters to populated areas, as allowed under an IDF policy … or even closer, as sometimes happened, it greatly increases the likelihood of civilian casualties.

When the shells explode they can spread about 2,000 fragments in all directions. Sometimes they fail to explode and “become potentially explosive duds,” according to Human Rights Watch.

“Israel Military Industries, a state-owned arms producer and exporter, produces the M107 shell, although Israel has also imported 155 mm shells from the United States,” Human Rights Watch says.

What this means in practice is that Israeli shelling is indiscriminate because an “error radius” of 25 meters in a densely populated Gaza neighborhood like Shujaiya is as good as firing randomly into people’s houses.

Four times as many shells as during “Cast Lead”

And this is corroborated from Israeli sources, in particular a 15 August article inHaaretz by Gili Gohen, which explains that “artillery shells are considered ‘statistical shooting,’ which does not enable hitting targets accurately.”

Cohen adds: “155 mm shells are generally shot toward an area 50 by 50 meters; hitting anywhere within this area is considered by professionals hitting the target. In densely constructed areas like the Gaza Strip, such an area could include more than five buildings.”

The IDF employed an exceptional amount of firepower during combat in the Gaza Strip, including in densely built areas. According to partial data provided by the army on 29 July, after three weeks of combat (of which 12 days were in the course of ground operation) approximately 30,000 shells had been shot by that time. The ground operation continued for more than one additional week, so we can estimate that the final number of shells shot is significantly higher.

By comparison, during the 2009 Cast Lead operation, the IDF shot about 8,000 artillery shells. Of that number, some half (4,000) were smoke shells. About one thousand shells were illuminating shells and the remainder, some 3,000, were explosive shells. During that operation the forces had been instructed to refrain from shooting into constructed areas, excluding exceptional cases, where firepower was needed to rescue forces. Most of the shooting at that time was done into open spaces, or the margins around the constructed area. An estimate can be made that the total number of artillery shells shot during Protective Edge is more than four times as high as during Cast Lead.

Cohen explains that on 20 July alone, “some 600 explosive artillery shells were shot within one hour” into the eastern Gaza City neighborhood of Shujaiya.

When such immense and inaccurate firepower is used as part of the “Hannibal Directive” – a procedure meant to ostensibly thwart the capture of soldiers – there can only be one real intent: to kill the soldier and everyone else in his vicinity.

In this video, Israeli soldiers and mystics can be seen dancing and singing to bless M107 artillery shells before they are fired into Gaza:

Tank guns are just another form of “statistical shooting,” so it can be expected that many of the estimated 23,400 tank shells fired at Gaza are also responsible for large numbers of civilian deaths, injuries and destruction even where Israel claims it was not specifically targeting homes, schools, hospitals and mosques.

But Israel has gone to great lengths to make its tank shells even more indiscriminate and lethal.

We know from Haaretz that the Israeli army was using Kalanit and Hatzav type tank shells in the attack on Gaza. Both were “used on a massive scale for the first time in Operation Protective Edge” – the name Israel has given its current assault on Gaza.

For “terrorists” one can, of course, simply substitute the word “humans,” and for “cover” one can substitute words like “house,” “school,” or “mosque.”

Israel is so proud of this shell that it won “Israel’s prestigious Defense Prize for 2011,” the Post says.

One of the features of the Kalanit tank shell is precisely that it kills people over a very wide area, as the Israeli army’s “Lt.-Col. M.” told the Post: “Until now, a tank would fire traditional shells at cells which would have to be extremely accurate, but now due to the dispersion, it can hit cells even if the shell does not detonate exactly over where they are.”

Danny Peretz, the head of the team that developed the shell, “explained that the need for the Kalanit came up because of the change in the type of warfare Israel faced on the modern battlefield, particularly asymmetric conflicts.”

“We are no longer speaking about just tanks against tanks, but you need to be able to hit people inside buildings and people outside where they are approximately hiding,” he told the Post. “The Kalanit can do both of these missions with the same shell.”

Mortar shells

It is unclear if the number of mortar shells Israel fired is included in the overall estimate for artillery – I was unable to find a separate estimate for mortars. A mortar is a type of artillery.

It is typically much shorter range than, say, a tank gun or a 155 mm artillery piece, and the explosive shell is lobbed on a high trajectory. It is definitely another form of “statistical shooting” but generally far less accurate than other weapons.

Yet this lethal and indiscriminate weapon was used on a huge scale. This video, originally broadcast on Israeli television, in a report on female gunners, shows one artillery unit made up of four vehicle-mounted large caliber mortars firing shells towards Gaza at a regular rhythm of four shells every two minutes.

At first the soldiers are firing smoke shells but then they are asked to use explosives, sending “rescuing fire” towards “two targets near a built up area.”

The female gunners can be seen scrawling birthday greetings to friends and such messages as “To Adi, Good luck with the new job!” on the mortar shells before blasting them into Gaza.

In between volleys, the gunners take breaks to eat meals of sushi.

Bombs dropped from the air

Israeli military sources have been less forthcoming about the number of bombs dropped from the air, but there have been some important clues.

On 10 July, the fourth day of Israel’s current assault on Gaza, The Jerusalem Postreported, citing a “senior military source”:

Around 800 tons of explosives have been fired by air force jets on targets this week, the source said. The IAF’s [Israel Air Force] current rate of fire is double that of Operation Pillar of Defense, launched in 2012 to stop Hamas rocket fire from Gaza. “We’ll see this trend increasing, as part of our firepower policy,” he said.

At that rate – not accounting for the promised increase – the tonnage of bombs could easily exceed six thousand tons over the course of a month.

And there was almost certainly an increase. On 20 July in Shujaiya, for example,according to Haaretz, Israeli warplanes carried out “a broad aerial attack that included about 100 one-ton bombs.” That was only in one location; Israeli warplanes were bombing all over Gaza as well.

It would take major on-the-ground research to identify them all, although Hazem Abu Murad and his team identified some of the types: the one-ton MK84 bombs that have a destructive radius of 300 meters and GBU laser-guided bombs, which have beenphotographed just before they struck buildings in Gaza.

These details of Israel’s ongoing bombardment of Gaza are important: if human rights researchers can collect the evidence of the weapons and equipment used in Israeli war crimes and crimes against humanity, it can help to make accountable not just those who ordered the weapons fired but also those who supplied them.

The staggering amount of weapons Israel has used to inflict so much indiscriminate harm underscores the urgency of calls for an arms embargo on Israel. It also highlights that Israel, an undeclared possessor of nuclear weapons, must urgently be brought under international control and monitoring.

But it is important not to lose sight of the big picture: no claim of “self-defense” could ever justify dropping this much explosives so indiscriminately and so deliberately on a captive civilian population.

Those who justify it as “self-defense” are complicit in mass murder.

It is also a mistake to look for a “military” explanation for Israel’s actions.
